Title: Improved heat sensitive alarm device
IPC: G08B17/00
Filed: 1928-12-14
Abstract: 309,120. Bory, G. H. L. G. April 5, 1928, [Convention date]. Lamp-failure alarms.-In an alarm device of the sagging-wine type, the wire 1 is enclosed in a perforated tube 10, and is made fast at one end to an adjusting screw 6, and at the other end to the free end of a leaf spring 11 secured to the tube. The tube is suspended by springs 4 to damp vibration. When the wire 1 is cold, it holds the end of the spring in contact with a screw 9 in an alarm circuit. When the wire is heated and expands, it allows the spring to move in a direction perpendicular to the wire, breaking the contact A washer 12 forms a dust-proof enclosure for the contacts. In a modification, Fig. 7, adapted for signalling that a lighted lamp has become extinguished, the tube 2 has a heatinsulating lining, as of asbestos, and an aperture 16 closed by a pane of mica. The aperture is arranged above the lamp 17. While the latter is alight, the wire 1 is expanded, and the alarm circuit is closed at 9, 11. The electromagnet 20 then attracts its armature 21, opening the alarm lamp circuit 22, 23. If the lamp is extinguished, the wire contracts and breaks contact at. 9, 11, the armature 21 is released, and the lamp 23 is lighted. The alarm circuit may include a bell, an indicator 19, and a hand-switch 25. Alternatively, the wire may be arranged to close the circuit when the lamp is extinguished. The Specification, as open to inspection under Sect. 91 (3) (a) comprises also a construction, Fig. 1 (Cancelled), wherein the wire 1 is enclosed in a casing 2 formed of perforated angle irons, is made fast at both ends, and passes over the hooked end 8 of contact spring 7 normally held by the wire in contact with a contact 9 in an alarm circuit. Sagging of the wire opens the circuit. This subject-matter does not appear in the Specification as accepted.

Patent GB-372258-A (GB)
Abstract: 372,258. Fluid-actuated valves. AKT.- GES. DER MASCHINENFABRIEKEN ESCHER, WYSS, ET CIE, 19, Hardturmstrasse, Z³rich, Switzerland. Jan. 28, 1932, No. 2600. Convention date, Jan. 29, 1931. [Classes 69 (ii) and 135.] Regulating apparatus in which a movably arranged deflecting body acted on by the physical characteristic to be regulated dips more or less deeply into a jet of. fluid directed by at least one outlet nozzle towards at least one receiving nozzle to control the regulating apparatus, has the outlet and receiving nozzles arranged in a sliding body. This body may move along the path of the deflecting body or at right-angles thereto and may be coupled to the main valve to give a follow-up action or may be controlled by a second characteristic. The Fig. shows the invention applied to a pressure regulating valve. Oil discharged by a pump 9 passes from a nozzle 4 to a receiving nozzle 5 and thence by a conduit 15 to the space above a spring-loaded piston 10 coupled to the main valve 11. The passage of oil between the jets 4, 5 is more or less interrupted by a deflecting member 6 formed on a lever 1 adjustably loaded by a spring 2 and operated by a bellows 8 subject to the pressure in the main conduit admitted through a pipe 14. The jets 4, 5 are formed in a member 25 connected by a link 24 and lever 23 to the piston rod 21 to give a follow-up action. Instead of being coupled to the main piston it may be actuated by an electromagnet or a second pressure responsive device or the like. The member 25 may have a manually actuated adjusting member, this being particularly necessary when a thermostat is used in place of the bellows 8. In a modification the nozzles 4, 5 are formed in a differential piston arranged either to actuate a main or relay valve. In this form the discharge jet or both jets is or are arranged at an angle to the axis of the piston to give a follow-up action. Compressed air or gas may be used instead of liquid to provide the jet.

Filed: 1954-12-24
Abstract: 773,340. Packaging plastic material. JOHNSON & CO. (LONDON), Ltd., A. Dec. 28, 1955 [Dec. 24, 1954], No. 37365/54. Class 94(1). The outlet of a machine which produces margarine continuously is coupled by a flange 2 to a conduit 1 through which the margarine is fed to an intermittently-operated packaging machine having its inlet coupled to a flange 3. A tube 4 is secured in a lateral aperture in the conduit and forms a cylinder for a piston 8 having a skirt 9 formed with a flange 10 and covered with a sleeve 11 of synthetic plastic. A sleeve 5, formed with apertures 24, is secured to the tube 4 and bolted to a closure plate 7 which supports a hollow rod 12 formed with a head 16 provided with a washer 19 engaging the interior of the skirt 9. Compressed air is admitted through the rod 12 to the interior of the piston so that when the inlet of the packaging machine is open the latter occupies the position shown with the flange 10 abutting the end of the tube 4. When the inlet of the packaging machine is closed, the pressure of the margarine forces back the piston against the air pressure so that the tube 4 forms a chamber accommodating the temporary excess of material, the latter being expelled into the conduit when the inlet is reopened. If the pressure of the margarine exceeds a predetermined value, the outward movement of the piston is sufficient to uncover a discharge orifice 22 in the tube 4.

Title: Conversion of 1,8-p-menthadiene-3-ol to acyclic compounds
IPC: C07C45/51
Filed: 1957-12-03
Abstract: Citral and isocitral are obtained by subjecting trans-1,8-p-menthadiene-3-ol to pyrolysis, and separating the required aldehydes from the unchanged menthadienol in the pyrolysate, e.g. by fractional distillation or by sulphite extraction.  The pyrolysis can be conducted in the liquid or vapour phase.  If only citral is desired, the pyrolysate can be treated with alkali to isomerize the isocitral to citral. Reaction of the pyrolysate with acetone in the presence of a condensing agent yields pseudo-ionone. Some hydrolysis may take place during the working-up of the pyrolysate by chemical means so that some 2-methyl-2-heptene-6-one is produced.  In Example 2, pure menthadienol is pyrolysed by adding the liquid dropwise down the side of a vertical iron pipe at 390 DEG -415 DEG C.  The pyrolysate, which has a strong lemon odour and contains about 50% of carbonyl compounds, is added to a solution containing acetone, water and sodium hydroxide.  The mixture is stirred at 25 DEG -30 DEG C. for 24 hours; then water is added, and the two liquid layers are separated.  The organic material is washed with saturated sodium bicarbonate solution, dried with anhydrous sodium sulphate, and then subjected to fractional distillation under reduced pressure. Eleven fractions are collected, and are examined by infra-red and ultra-violet spectroscopy.  In addition to unchanged menthadienol, the following products are identified: pseudo-ionone, citral, isocitral and 2-methyl-2-heptene-6-one.  Specification 755,667 is referred to.
